Abstract
The utility model pertains to an auxiliary device of medical appliance, in particular to an air pipe guide tube capsule internal pressure monitor program, which comprises a display pipe with holes at two ends, a spring and a plunger, wherein, the plunger and spring are placed in the display tube, one end of the plunger in the display tube is placed and communicated with the charge bag, and the spring is between the plunger and the display tube. The technical project of the utility model is monitoring the pressure in the cover sack via the plunger and the spring of the display tube via the function of gas pressure.
Description
Technical field: the utility model belongs to a kind of servicing unit of medicine equipment, especially relates to a kind of cuff for endotracheal catheter inspection of inner pressure device.
Background technology: and the patient of row lung ventilator treatment limited to respiratory function, need conduit is inserted patient's tracheae, for preventing tracheae gas leakage, need to give the cover capsule in the tracheae outside inflate.The size of aeration quantity is very important to the patient, and suitable aeration quantity not only can guarantee the patient is implemented lung's positive airway pressure, prevents the mistake suction, also can avoid the generation of complication.At present common way is to give supravasal sleeve bag gas-filling when ventilation, and the feel tension force when being accustomed to pinching gas cell with hand clinically and the size of range estimation gas cell are estimated what of aeration quantity, the quantizating index that neither one is definite.Since not the actual pressure in the capsule of overcoming difficulties, so blindness is arranged.A kind of cover bag pressure force controller is arranged, but it costs an arm and a leg inconvenient clinically popularizing abroad.It is 01243237.7 " tracheal catheter pressometer " that China Intellectual Property Office discloses the patent No., though it is with low cost, measures accurately, and it is complicated that structure shows slightly, and volume is big slightly, inconvenience when clinical manipulation uses.
Summary of the invention: the purpose of this utility model just provide a kind of easy to operate, measure cuff for endotracheal catheter inspection of inner pressure device accurately.
According to the air pressure balance principle, the utility model is provided with a pressure monitor in a side of original gas cell draft tube, and this monitor is simple in structure, and volume is small and exquisite, and intuitive display, accurate is convenient to monitoring; Solved the not enough separately of above-described sleeve bag gas-filling device, pressure control equipment and pressometer.
A kind of cuff for endotracheal catheter inspection of inner pressure device, by gas cell 1, the draft tube 2 and the connecting pipe 8 that have air admission hole 3 are formed, the end that draft tube 2 has an air admission hole 3 is in the outside of gas cell 1 one ends, the other end extend in the gas cell 1 and with gas cell 1 in be communicated with, conduit 8 is communicated with the cover capsule in the gas cell 1 and the tracheal catheter outside, it is characterized in that: a side of draft tube 2 is fixed with a display tube 5 that has venthole 4, one end of display tube 5 be in the gas cell 1 and with gas cell 1 in be communicated with, venthole 4 is opened an end that is in gas cell 1 outside at display tube 5, piston 7 places an end that is communicated with gas cell 1 in the display tube 5, and spring 6 places between display tube 5 inner carriers 7 and the venthole 4.
Description of drawings: Fig. 1 presses the detector arrangement synoptic diagram in the utility model cuff for endotracheal catheter, wherein:
1-gas cell, 2-draft tube, 3-air admission hole
4-venthole, 5-display tube, 6-spring
7-piston, 8-connecting pipe
Specific embodiments: in conjunction with the accompanying drawings, the implementation procedure of narration the utility model cuff for endotracheal catheter inspection of inner pressure device: the side in the draft tube 2 of gas cell 1 has increased a pressure monitor of being made up of the display tube 5 that has venthole 4, spring 6 and piston 7.The mounting connection structure of this pressure monitor and be with the connected mode of gas cell 1: display tube 5 is the transparent tube of both ends open, the opening of one end is a venthole 4, piston 7 places the end in the display tube 5, spring 6 places between display tube 5 inner carriers 7 and the venthole 4, and the end that display tube 5 is equipped with piston 7 is in the gas cell 1 and with gas cell 1 and is communicated with.For ease of clinical manipulation, according to clinical experience determine can guarantee autonomous respiration of patient lung and control breathing the time prevent reflux erroneous aspiration, can keep mucous membrane that enough blood supply amount states intracapsular pressure value of trapping is arranged again, can be on display tube 5 calibrate, do a mark on the spring 6 in display tube 5 or connect a pointer.
Manipulate: in gas cell 1, inflate by draft tube 2, the gas that enters in the gas cell 1 enters in the cover capsule that is enclosed within tracheal catheter by connecting pipe 8, along with increasing of gas, pressure in cover capsule and the gas cell 1 also increases thereupon, when the cover capsule seals air flue, because gas cell 1 and cover capsule are communicated with by connecting pipe 8, air bag 1 is identical with the air pressure of cover in the capsule, under the gas effect in air bag 1, piston 7 in the display tube 5 promotes spring 6 and moves to the direction of venthole 4, when the mark on the spring in the display tube 56 (or be connected on the spring 6 pointer) when being in the scale value scope on the display tube 5, stop to inflate in gas cell 1, the interior pressure that overlap in the capsule this moment is exactly clinical required scope.
The utility model cuff for endotracheal catheter inspection of inner pressure device is reasonable in design, simple in structure, easy to operate, directly perceived, is convenient to promote.
